WINDOW-CONTROL MECHANISM.

Application filed May 9,

This invention relates to window control mechanism, and moreparticularly to mechanism for vertically adjusting windows of motorvehicles.

It is the object of the invention to provide a comparatively simplemechanism adapted to be enclosed within the lower portion of a vehicledoor to actuate the vertical travel of a window member in the upperportion of the door ant serving to automatically maintain such windowmember in any desired position of adjustment.

A preferred embodiment of the invention is illustrated in theaccompanying drawings wherein,

Figure 1 is a fragmentary inner side view of a motor vehicle door of thesliding window type, equipped with the herein described controlmechanism and having a portion of the trimming broken away to disclosesaid mechanism. Fig. 2 is a vertical section of the door on the line 22in Fig. 1. Fig. 8 is an inner side elevation of the control mechanismembodying the invention removed from the door. Fig. d is a sectionthereof on the line 14: in Fig. 3. Fig. 5 is a section on the line 5-5in Fig. 3, and Fig. 6 is a perspective elevation of the swivel mountingfor the screw stem of the mechanism.

Referring to the drawings, 1 designates a motor vehicle door and 2 awindow opening in the upper portion of said door for which a closure isformed by a vertically slidable plate of glass 3, which, when lowered,enters the customary well or chamber 1- formed in the lower portion ofthe door. The door frame includes a crosspiece 5 disposed at the upperend of the well 1 at the inner side of the glass 3. A plate 6 is mountedon the outer side of the crosspiece 5 near one end thereof and covers anopening 7 provided through the cross-piece.

The actuating mechanism for the glass 3 comprises an arm 8 pivoted atone end to an offset tongue 9 projecting inwardly within the well 4 fromthe lower end of the plate, in the present instance, a distance belowthe lower edge of the crosspiece 5. The other end of the arm 8 carries aperipherally grooved roller 10 which engages a channeled sheet metalstrip 11 secured to the bottom edge of the glass to support the glassand to travel lengthwise of said strip when the arm 1823.

is swung to raise or lower the glass. A nut 12 is swiveled upon the arm8 adjacent its pivoted end and engaged by the lower threaded end portionof the upwardly extending stem 18, the upper portion of which isjournaled in a mounting 1 1, which is sn'iveled in the plate 6 forswinging movements in a plane parallel thereto The swivel mounting 1 1,in the present instance, is of stamped sheet metal construction and isprovided at its upper end with a pair of tongues 15 spacedlongitudinally of the mounting and having axially aligned "bearings 16for receiving the upper journal end of the screw stem 13. The lower endof the mounting 14 is provided with a laterally projecting tongue 17from which a stud 18 rigidly projects upwardly through an enlargedopening 19 in the plate 6. The stud 18 is secured at its inner endwithin an open ing 20 in the tongue 17.

A small beveled pinion 21 is fixedly mounted on the screw stem 18between the tongues 15 of the swivel mounting and is engaged and drivenby a large bevel gear 22 which is journaled on the stud 18 and has itshub, projecting through and j ournaled in the opening 19 of the plate 6.A crank arm 23 is loosely mounted on the stud 18 without the hub of thegear 22 and is adapted to have keyed or interengaged connection with thegear hub to cause the gear and crank arm to turn in unison. A screw24pis threaded into the outer end of the stud 18 and engages the hub endof the crank arm 23 to retain it in assembled position with respect tothe gear 22. It is evident that a turning of the crank arm 23 willcommunicate a turning movement to the screw stem 13 through theinterposed gearing and that the turning of the stem will effect araising or lowering of the window supporting arm 8 due to the threadingof the stem through the swivel nut 12 carried by the arm.

The weight of the glass on the arm 8 is counterbalanced, in the presentinstance, by one or more springs 25, which connect the arm 8 at a pointnear its inner end to a flange 26 struck inwardly from the upper end ofthe plate 6.

All the described mechanism, with the exception of the crank arm 23, isconcealed within the well 4 of the door and carried as a unit by theplate 6 to facilitate assembling or removal of the same for repair orsubstitution. A portion of the described mechanism is disposed withinthe opening 7 of the cross-piece 5 so that the door or the well 4:therein does not need to be made of greater thickness than is customaryin doors of this class in order to accommodate the glass controllingmechanism.

In the operation of the control mechanism, when it is desired to adjustthe window member 3, the handle 23 is rotated in the desired direction.This rotation is transmitted through the gearing 22, 21 to the stem 13,which through engagement with the nut 12, effects the raising orlowering of the arm 8, according to the direction of rotation of thehandle. As the nut is constrained to travel in a circular arc the stem13 swings through a slight angle of the vertical, the divergence fromthe vertical being a maximum when the arm 8 is horizontal. The necessityfor swivel mounting of the nut 12 on the arm 8 and for the swiveling ofthe member l l arises from this slight angular movement of the stem 13.It will be apparent that the engagement of the stem 13 with the nut 12provides an automatic lock such as will serve to maintain any positionto which the window member 8 may be adjusted.

We wish it understood that our invention is not limited to any specilicconstruction, fllltll1l;l11811t or form of the parts, as it is capableof embodiment in numerous i'orms without departing from the spirit ofthe claims.

hat we claim as our invention is:

1. The combination with a slidable window member, of a frame guiding themovements of said member, a plate secured to said frame and having anopening therein, a gear having a hub portion journaled in and projectingthrough the plate opening, a swivel mount carried by the gear for swivelmovements coaXially therewith, an arm pivoted at one end to said plateand having supporting engagement at its other end with the windowmember, a swivel nut carried by the arm, a stem journaled in said swivelmount and threaded through the nut, driving connection between said gearand stem, and means for rotating the gear.

2. The combination with a slidable window member, of a frame guiding themovements of said member, a plate secured to said frame and having anopening therein, a gear having a hub portion journaled in and projectingthrough the plate openin a swivel mount carried by the gear for swivelmovements coaxially therewith, an arm pivoted at one end to said plateand having supporting engagement at its other end with the windowmember, a swivel nut carried by the arm, a stem journaled in said swivelmount and threaded through the nut, driving connection between said gearand stem, means for rotating the gear, and counterbalancing meansconnected to said. arm.

3. The combination with a slidable win dow member, 01'. a frame guidingthe movement of said member and including a recessed cross piece, aplate secured to said frame, an arm pivotally mounted upon said plateand operatively connected to said window member, a swivel nut carried bysaid arm, a stem threadedly engaging said nut, gearing upon said platewithin the recess in said cross piece, said gearing being connected tosaid arm, and window counterbalancing means extending within the recessof said cross piece.

In testimony whereof we have hereunto signed our names to thisspecification.
